전자식 솔레노이드 에어밴트Electronic Solenoid Air Vent

본 발명은 전자식 솔레노이드 에어밴트에 관한 것으로, 보다 자세하게는 난방 및 유체이동 시 배관 내로 순환되는 유체 속의 공기를 제거하여, 배관 내 부식을 방지하고, 소음 및 진동을 감소시키며 유속의 증가로 인한 효율을 개선하는 전자식 솔레노이드 에어밴트에 관한 것이다.The present invention relates to an electronic solenoid air vent, and more particularly, to remove the air in the fluid circulated into the pipe during heating and fluid movement, to prevent corrosion in the pipe, to reduce noise and vibration, and to improve efficiency due to the increase in flow rate.

또한 보일러에서 난방배관(공급관)으로 난방 수를 공급할 곳에 에어밴트 혹은 에어어레스트를 설치하여 공기를 제거한 난방 수를 공급하여야 효율이 증대되며 공기가 충분히 제거되지 못하면 난방배관(40)에 공기가 차서 소음 및 에어포켓(큰 공기방울) 인한 물의 흐름에 저항이 발생하고, 열효율이 감소되는 등 여러 문제가 발생한다. 이에 따라 난방배관(40) 내부의 공기를 항시 배출하여야 하는데, 종래 에어밴트는 플롯트를 이용한 방법이 사용되므로 도출구에서 공기와 물이 섞여 나오거나, 구멍이 적어 이물질로 인한 노줄 막힘 현상으로 2차 피해가 발생하는 문제점이 존재하여 기존의 에어밴트는 물이 언제 나올지 모르는 불안감으로 노즐을 막아버리기 때문에 에어밴트의 본래 기능을 다하지 못하고 있는 실정이다.In addition, the efficiency is increased only by supplying heating water from which air is removed by installing an air vent or air arrester to supply the heating water from the boiler to the heating pipe (supply pipe). If the air is not sufficiently removed, the air is filled in the heating pipe 40 to make noise. And problems such as resistance to the flow of water due to air pockets (large air bubbles) and a decrease in thermal efficiency. Accordingly, the air inside the heating pipe 40 should always be discharged. Since the air vent is a conventional method using a float, air and water are mixed in the outlet, or there are few holes, resulting in clogging due to foreign substances. There is a problem that the car damage occurs, so the existing air vent is blocking the nozzle with anxiety of when the water will come out of the situation is not able to fulfill the original function of the air vent.

도 2는 발명의 실시예에 따른 에어밴트의 구성을 나타낸 측단면도이다. 도시된 바와 같이, 발명의 실시예에 따른 에어밴트(100)는 연결관(105), 가림막(110), 에어밴트(100)의 내부(135)에 위치하고 내부에 자석을 포함하는 부레 (120), 리드 스위치(125) 및 노즐차단부(200)를 포함한다.Figure 2 is a side cross-sectional view showing the configuration of the air vent according to an embodiment of the present invention. As shown, the air vent 100 according to an embodiment of the invention is located in the connection pipe 105, the screen 110, the interior 135 of the air vent 100, including a magnet 120 therein , A reed switch 125 and a nozzle blocking unit 200.

도시된 바와 같이 에어밴트(100)는 수평으로 배치될 수 있고, 부레(120)가 상하 이동 시, 이동 축에 리드 스위치(125)가 내장되어 부레(120)(자석)의 높이로 수위를 감지한다.As shown, the air vent 100 may be horizontally disposed, and when the bure 120 moves up and down, a reed switch 125 is built in the moving shaft to sense the water level at the height of the bure 120 (magnet). do.

연결관(105)은 난방배관과 직접 연결될 수 있고, 또한 난방 공급관에 기수분리기, 공기를 포집하는 세퍼레이트(미도시)와 연결되어 난방배관과 간접적으로 연결될 수도 있다.The connecting pipe 105 may be directly connected to the heating pipe, or may be connected to a separator (not shown) that collects air in the heating supply pipe and indirectly connected to the heating pipe.

에어밴트(100)의 측면(130)은 단면이 상부를 향해 좁아지는 피라미드의 구성으로 형성될 수 있으나 이에 대해 한정하지는 않는다.The side surface 130 of the air vent 100 may be formed in a pyramid configuration whose cross section is narrowed upward, but is not limited thereto.

에어밴트(100)의 내부(135)에는 부레(120)가 위치한다. 부레(120)는 밀도가 물보다 낮으며 공기보다 높은 물질로 형성될 수 있고 재질에 대해 한정하지 않는다. 부레(120)는 이동축(260)을 기준으로 상하로 이동하게 되며, 부력에 의해 수면의 상방으로 뜨게 된다.In the interior 135 of the air vent 100, the bure 120 is located. The bridle 120 may be formed of a material having a lower density than water and higher than air, and is not limited thereto. The bure 120 is moved up and down based on the moving shaft 260, and floats above the water surface by buoyancy.

에어밴트(100)의 내부(135)에 공기가 차게 되면, 부레(120)가 공기의 부피만큼 아래로 내려가게 된다. 공기에 의해 부레(120)가 일정 높이 이하로 내려가게 되면 솔레노이드(230)가 동작하여 노즐(140)을 통해 에어밴트(100) 내부(135)의 공기가 외부로 배출된다. 노즐차단부(200)의 동작에 대해서는 도 3을 참조하여 상세히 기술한다.When the air is filled in the interior 135 of the air vent 100, the bure 120 is lowered by the volume of air. When the bure 120 is lowered to a predetermined height or lower by air, the solenoid 230 operates to discharge the air in the air vent 100 135 from the outside through the nozzle 140. The operation of the nozzle blocking unit 200 will be described in detail with reference to FIG. 3.

도 3은 발명의 실시예에 따른 에어밴트를 구성요소별로 분리하여 나타낸 측단면도이다. 도 2와 동일한 구성요소에 대해서는 그 도면부호를 생략한다.Figure 3 is a side cross-sectional view showing the air vent separated by components according to an embodiment of the present invention. The same reference numerals are omitted for the same components as in FIG.

노즐차단부(200)는 고무패킹(205), 마그넷(210), 스프링(211), 실린더(220), 코일이 권선된 솔레노이드(230)를 포함한다. 리드 스위치(125)를 동작시키는 부레(120)와 솔레노이드(230)에 구동 전원을 공급하는 전원부(미도시)를 포함하며, 전원으로는 상용전기(AC) 또는 이차전지(DC)로 형성될 수 있다.The nozzle blocking part 200 includes a rubber packing 205, a magnet 210, a spring 211, a cylinder 220, and a solenoid 230 wound with a coil. It includes a power supply unit (not shown) for supplying driving power to the bure 120 and the solenoid 230 for operating the reed switch 125, the power source may be formed of a commercial electric (AC) or secondary battery (DC). have.

도시된 바와 같이 마그넷(210)의 일단에는 고무패킹(205)이 연결되고 마그넷(210)의 타단에는 탄성부재(211)가 연결된다. 탄성부재(211)는 예를 들어, 스프링일 수 있다. 노즐차단부(200)에는 실린더(220)와 솔레노이드(230)를 고정시키는 너트(250)가 포함된다.As shown, the rubber packing 205 is connected to one end of the magnet 210 and the elastic member 211 is connected to the other end of the magnet 210. The elastic member 211 may be, for example, a spring. The nozzle blocking part 200 includes a nut 250 for fixing the cylinder 220 and the solenoid 230.

고무패킹(205)은 솔레노이드(230)가 동작하여 탄성부재(211)의 탄성력 이상으로 실린더(220)에 삽입된 마그넷(210)을 끌어당기는 동안에는 노즐(140)과 분리되어 에어밴트(100) 내부(135)의 공기를 밖으로 배출하고, 솔레노이드(230)가 동작하지 않는 동안에는 탄성부재(211)의 탄성력에 의해 고무패킹(205)이 노즐(140)과 접하게 되어 밀폐 상태를 유지한다.The rubber packing 205 is separated from the nozzle 140 while the solenoid 230 is operated to pull the magnet 210 inserted into the cylinder 220 above the elastic force of the elastic member 211, thereby being separated from the air vent 100. While the air of the 135 is discharged and the solenoid 230 is not operated, the rubber packing 205 is in contact with the nozzle 140 by the elastic force of the elastic member 211 to maintain a closed state.

부레(120)는 물보다 밀도가 낮은 물질로 형성되며, 수면에 접한다. 가림막(110)에는 도시된 바와 같이 가림막(110)를 관통하는 적어도 하나의 홀(111)이 형성된다. 홀(111)이 형성된 가람막(110)을 통해 물의 수면의 높이가 급격히 변화하는 것을 방지하여 동작의 안정성 및 신뢰성을 향상시킬 수 있다. 홀(111)은 전체 가림막(110) 면적의 절반 이하의 면적으로 형성될 수 있다.The bridle 120 is formed of a material having a lower density than water and is in contact with the water surface. At least one hole 111 penetrating the shielding film 110 is formed in the shielding film 110. The height of the surface of the water may be prevented from being changed rapidly through the light film 110 having the holes 111 formed therein, thereby improving stability and reliability of the operation. The hole 111 may be formed to have an area less than half of the area of the entire blocking film 110.

상기에서 기술한 바와 같이, 에어밴트(100)의 내부(135)에 물이 가득 차면 부레(120)와 이동축(260)의 리드 스위치(125)간의 거리가 멀어져 리드 스위치(125)가 OFF 되어 솔레노이드(230)가 동작하지 않는다. 이에 따라 마그넷(210)의 타단에 연결된 탄성부재(211)의 탄성력에 의해 고무패킹(205)이 노즐(140)과 접하게 되어, 에어밴트(100)의 내부(135)는 밀폐된다. 즉 외부로부터 에어밴트(100)의 내부(135)로 공기가 유입되지 않고, 에어밴트(100)의 내부(135)로 공기가 외부로 배출되지 않는다.As described above, when the interior 135 of the air vent 100 is filled with water, the distance between the bure 120 and the reed switch 125 of the moving shaft 260 is increased so that the reed switch 125 is turned off. Solenoid 230 does not operate. Accordingly, the rubber packing 205 is in contact with the nozzle 140 by the elastic force of the elastic member 211 connected to the other end of the magnet 210, the interior 135 of the air vent 100 is sealed. That is, air does not flow into the interior 135 of the air vent 100 from the outside, and air is not discharged to the interior 135 of the air vent 100.

에어밴트(100)의 내부(135)에 공기가 차게 되면, 부레가(120)가 공기의 부피만큼 아래로 내려가게 된다. 또한 부레(120)가 아래로 내려감에 따라 부레(120) 이동 축에 위치하고 있는 리드 스위치(125)가 동작하게 된다. 공기에 의해 부레(120)가 일정 높이 이하로 떨어지게 되면 부레(자석)(120)의 위치와 리드 스위치(125)가 근접하게 되어. 부레(120)의 이동 축의 리드 스위치(125)가 턴온되어 솔레노이드(230)가 동작하게 된다. 즉, 솔레노이드(230)에 전원이 공급되어 마그넷(210)의 타단에 연결된 탄성부재(211)의 탄성력 이상으로 마그넷(210)을 끌어당기게 된다.When the air is filled in the interior 135 of the air vent 100, the burega 120 is lowered by the volume of the air. In addition, the reed switch 125 located on the moving shaft of the bure 120 operates as the bure 120 is lowered. When the air bubble 120 falls below a predetermined height by air, the position of the air bubble 120 and the reed switch 125 are close to each other. The reed switch 125 of the moving shaft of the bure 120 is turned on so that the solenoid 230 operates. That is, power is supplied to the solenoid 230 to attract the magnet 210 above the elastic force of the elastic member 211 connected to the other end of the magnet 210.

이에 따라 마그넷(210)의 일단에 연결된 고무패킹(205)이 노즐(140)과 이격되어, 에어밴트(100)의 내부(135)가 개방된다. 즉 에어밴트(100) 내부(135)의 공기가 노즐(140)을 통해 외부로 배출된다.Accordingly, the rubber packing 205 connected to one end of the magnet 210 is spaced apart from the nozzle 140 to open the interior 135 of the air vent 100. That is, air inside the air vent 100 135 is discharged to the outside through the nozzle 140.

에어밴트(100) 내부(135)의 공기가 노즐(140)을 통해 외부로 배출됨에 따라 공기의 감소로 에어밴트(100)의 내부(135)에는 수압으로 물이 차게 된다. 이에 따라 부레(120)가 다시 위로 올라가게 되면 스위치 역할을 하는 리드 스위치(125)가 OFF 되어 솔레노이드(230)에 공급되는 전원이 차단되고, 이에 따라 마그넷(210)의 타단에 연결된 탄성부재(211)의 탄성력에 의해 마그넷(210)의 일단에 연결된 고무패킹(205)이 노즐(140)과 접하게 되어 에어밴트(100)의 내부(135)가 밀폐된다.As air inside the air vent 100 is discharged to the outside through the nozzle 140, water is filled in the inside 135 of the air vent 100 by hydraulic pressure due to the decrease of air. Accordingly, when the bure 120 rises up again, the reed switch 125 serving as a switch is turned off, and the power supplied to the solenoid 230 is cut off, and thus, the elastic member 211 connected to the other end of the magnet 210. The rubber packing 205 connected to one end of the magnet 210 is brought into contact with the nozzle 140 by the elastic force of the () to seal the interior 135 of the air vent 100.

노즐(140)의 일측에는 에어 배출 수동 보턴(240)이 형성된다. 이는 항시 닫혀있는 에어밴트(100)에서 수동으로 공기를 강제로 배출시킬 수 있는 장치로 입구에 에어 배출 수동 보턴(240)을 설치하여 이를 누르면 강제로 마그넷(210)을 뒤로 이동시켜 에어밴트(100) 내부(135)의 공기를 외부로 배출할 수 있다. 에어 배출 보턴(240)에는 탄성부재가 연결되어 수동 에어 배출 수동 보턴(240)을 누르는 동안에만 에어밴트(100) 내부(135)의 공기를 외부로 배출할 수 있다.On one side of the nozzle 140, the air discharge manual button 240 is formed. This is a device that can be forced to manually discharge air from the air vent 100, which is always closed, by installing the air discharge manual button 240 at the inlet and pressing it to force the magnet 210 to move backward to the air vent (100) The inside of the air 135 may be discharged to the outside. An elastic member is connected to the air discharge button 240 to discharge the air inside the air vent 100 135 to the outside only while the manual air discharge manual button 240 is pressed.

또한, 에어밴트(100)에는 데이터 저장부(미도시)가 형성될 수 있다. 데이터 저장부는 솔레노이드(230)의 동작에 관한 정보, 즉 외부로 배출되는 에어의 부피에 관한 정보를 저장할 수 있다. 구체적으로, 솔레노이드(230)의 시간별 동작 횟수, 동작한 시간, 동작 시간당 배출되는 에어의 부피 등의 정보를 저장하고, 네트워크를 통해 관련 정보를 외부로 전달할 수 있다. 이에 따라 고장유무 및 에어의 배출량에 관한 정보를 저장, 확인할 수 있으므로 자동화에 기여할 수 있게 된다.In addition, a data storage unit (not shown) may be formed in the air vent 100. The data storage unit may store information about the operation of the solenoid 230, that is, information about the volume of air discharged to the outside. In detail, information such as the number of times of operation of the solenoid 230, the time of operation, the volume of air discharged per operation time, and the like may be stored, and related information may be transmitted to the outside through a network. As a result, information on the presence of failure and the amount of air emissions can be stored and confirmed, thereby contributing to automation.

상기의 구성에 의해 에버밴트(100) 내부(135)의 공기를 신속하게 밖으로 배출시킬 수 있으므로 보일러의 열효율을 향상시킬 수 있다.By the above configuration, it is possible to quickly discharge the air in the interior 135 of the Evervant 100, it is possible to improve the thermal efficiency of the boiler.
